Maintain the Node

This chapter provides procedures for maintaining the Cisco ONS 15454.

Before You Begin

Before performing any of the following procedures, investigate all alarms and clear any trouble conditions. Refer to the Cisco ONS 15454 Troubleshooting Guide as necessary for general troubleshooting information and alarm or error descriptions.

This section lists the chapter procedures (NTPs). Turn to a procedure to view its tasks (DLPs).

NTP-A107 Inspect and Replace the Air Filter

This procedure ensures that the air filter is free from dirt and dust, which allows optimum air flow and prevents dirt and dust from entering the shelf.

Tools/Equipment

New air filter and pinned hex key tool

Prerequisite Procedures

None

Required/As Needed

As needed

Onsite/Remote

Onsite

Security Level

None

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Note The air filters are single-use only. They must not be cleaned and reused. This is a Telcordia NEBS requirement, GR-63-CORE Issue 4.

Note Air filters must be inspected every month. If they are dirty or clogged with dust, they must be replaced with a new air filter.

Caution If you install the air filter below 15454-CC-FTA (800-27558-xx), only filters with part numbers 700-23193-01 and 700-23194-01 can be used in this configuration.

Caution Although the filter can work with FTA3 if it is installed with either side facing up, it is recommended that you install it with the metal bracing facing up to preserve the surface of the filter. You must install the air filter with the metal bracing facing up with 15454-CC-FTA.

Note To install the air filter inside the air ramp unit (15454E-AIR-RAMP or 15454-AIR-RAMP), use the ETSI version of the air filter (15454-FTF2 or 15454E-FTF4).

Step 1 If the air filter is installed in the external filter brackets, slide the filter out of the brackets while being careful not to dislodge any dust that might have collected on the filter and proceed to Step 8. Figure 15-1 illustrates a fan-tray air filter in an external filter bracket.

Step 2 If the filter is installed below the fan tray and not in the external filter brackets, open the front door of the shelf assembly using the following substeps. If the front door is already open, proceed to Step 3.

a. Open the front door lock.

The ONS 15454 comes with a pinned hex key for locking and unlocking the front door. Turn the key counterclockwise to unlock the door and clockwise to lock it.

b. Press the door button to release the latch.

c. Swing the door open.

Step 3 Remove the front door (optional). If you do not want to remove the door or it is already removed, proceed to Step 4.

a. Detach the ground strap from either the door or the chassis by removing one of the Kepnuts.

b. Place the Kepnut back on the stud after the ground strap is removed to avoid misplacement.

c. Secure the dangling end of the ground strap to the door or chassis with tape.

Step 4 Push the outer side of the handles on the fan-tray assembly to expose the handles.

Step 5 Pull the handles and slide the fan-tray assembly one half inch (12.7 mm) out of the shelf assembly and wait until the fans stop.

Step 6 When the fans have stopped, pull the fan-tray assembly completely out of the shelf assembly.

Step 7 Gently remove the air filter from the shelf assembly. Be careful not to dislodge any dust that might have collected on the filter.

Step 8 Visually inspect the air filter material for dirt and dust.

Step 9 Replace the air filter with a new one if the air filter is dirty or clogged with dust.

Caution Do not leave the fan tray out of the chassis for an extended period of time because excessive heat can damage the ONS 15454 cards.

Step 10 Replace the air filter:

a. If the air filter is installed in the external filter brackets, slide the dry air filter all the way to the back of the brackets.

b. If the filter is installed below the fan-tray assembly, slide the dry/clean air filter into the recessed compartment at the bottom of the shelf assembly. Put the front edge of the air filter flush against the front edge of the recessed compartment. Push the fan tray back into the shelf assembly.

Caution If the fan tray does not slide all the way to the back of the shelf assembly, pull the fan tray out and readjust the position of the air filter until the fan tray fits correctly.

Note On a powered-up ONS 15454, the fans start immediately after the fan-tray assembly is correctly inserted.

Step 11 To verify that the tray is plugged into the backplane, ensure that the LCD on the front of the fan-tray assembly is activated and displays node information.

Step 12 Rotate the retractable handles back into their compartments.

Step 13 If you replace the door, also reattach the ground strap.

Step 14 Close and lock the door.

Step 15 Return to your originating procedure (NTP).

Stop. You have completed this procedure.

NTP-A108 Back Up the Database

Purpose

This procedure stores a backup version of the TCC2/TCC2P (software) database on the workstation running Cisco Transport Controller (CTC) or on a network server.

Tools/Equipment

None

Prerequisite Procedures

None

Required/As Needed

Required. Cisco recommends performing a database backup at approximately weekly intervals and prior to and after configuration changes.

Onsite/Remote

Onsite or remote

Security Level

Maintenance or higher

Note You must back up and restore the database for each node on a circuit path in order to maintain a complete circuit.

Note The following parameters are not backed up and restored: node name, and Internet Inter-ORB Protocol (IIOP) port. If you change the node name and then restore a backed up database with a different node name, the circuits map to the new node name. Cisco recommends keeping a record of the old and new node names.

Caution E1000-2 cards lose traffic for approximately 90 seconds when an ONS 15454 database is restored. Traffic is lost during the period of spanning tree reconvergence. The CARLOSS alarm appears and clears during this period.

Caution If you are restoring the database on multiple nodes, wait approximately one minute after the TCC2/TCC2P reboot has completed on each node before proceeding to the next node.

Caution TCC2P cards can be used in single IP address (repeater) and dual IP address (secure) modes. The secure mode has advanced features that affect database restore. A database from a secure node cannot be loaded on an unsecure repeater node. An unsecure repeater node database can be loaded onto a secure node but the database will follow the node characteristics (that is, become secure). A secure database cannot be loaded onto a TCC2; only TCC2P cards support secure mode. For more information about the dual IP-address secure mode, see the
"NTP-A169 Set Up CTC Network Access" procedure. Also refer to the "Management Network Connectivity" chapter in the
Cisco ONS 15454 Reference Manual.

Caution To avoid a node IP and secure IP ending up in the same domain after restoring a database, ensure that the node IP stored in the database differs in domain from that of the node in repeater mode. Also, after restoring a database, ensure that the node IP and secure IP differ in domain.

Note The following parameters are not backed up and restored: node name, and IIOP port. If you change the node name and then restore a backed up database with a different node name, the circuits map to the new renamed node. Cisco recommends keeping a record of the old and new node names.

Note ML-Series Ethernet cards must be reset after a database restore. For more information about restoring these cards, refer to the Ethernet Card Software Feature and Configuration Guide for the Cisco ONS 15454, Cisco ONS 15454 SDH, and Cisco ONS 15327.

Note If you want to revert to a previously used software load, consult the platform-specific upgrade documentation for instructions.

Step 1 Complete the "DLP-A60 Log into CTC" task at the node where you are restoring the database. If you are already logged in, continue with Step 2.

Step 2 Ensure that no BLSR switch events are present; for example, ring-switch east or west. In network view, click the Conditions tab and click Retrieve to view a list of conditions.

Step 3 If switch events need to be cleared, in node view click the Maintenance > BLSR tabs and view the West Switch and East Switch columns.

a. If a switch event (not caused by a line failure) is present, choose CLEAR from the drop-down list and click Apply.

b. If a switch event caused by the Wait to Restore (WTR) condition is present, choose CLEAR from the drop-down list and click Apply.

When a switch event is cleared, NO COMMAND appears in the column to indicate that the switch event is no longer in effect.

Note Complete database restore may be used only on a node that is removed from the network, and does not carry live provisioning traffic. This operation needs to be done by a live operator onsite, and must not use a remote connection.

Step 10 If you need to restore only the provisioning database (partial restore), do not check the Complete database (System and Provisioning) checkbox.

NTP-A163 Restore the Node to Factory Configuration

Purpose

This procedure reinitializes the ONS 15454 using the CTC reinitialization tool. Reinitialization uploads a new software package to the TCC2/TCC2P cards, clears the node database, and restores the factory default parameters.

Tools/Equipment

ONS 15454 SONET System Software CD, Version 8.5

JRE 5.0 is recommended to log into the node after reinitialization is complete. The reinitialization tool can run on JRE 1.3.1_02, JRE 1.4.2, or JRE 5.0.

Caution Cisco strongly recommends that you keep different node databases in separate folders. This is because the reinit tool chooses the first product-specific software package in the specified directory if you use the Search Path field instead of the Package and Database fields. You might accidentally copy an incorrect database if multiple databases are kept in the specified directory.

Caution Restoring a node to the factory configuration deletes all cross-connects on the node.

Caution Cisco recommends that you save the node database to safe location if you will not be restoring the node using the database provided on the software CD.

Note The following parameters are not backed up and restored when you delete the database and restore the factory settings: node name, IP address, subnet mask and gateway, and IIOP port. If you change the node name and then restore a backed up database with a different node name, the circuits map to the new renamed node. Cisco recommends keeping a record of the old and new node names.

NTP-A300 Viewing the Audit Trail Records

Purpose

This procedure describes how to view Audit Trail records. Audit trail records are useful for maintaining security, recovering lost transactions, and enforcing accountability. Accountability refers to tracing user activities; that is, associating a process or action with a specific user.

A window containing the most recent Audit Trail records appears as shown in Figure 15-4.

Figure 15-4 Viewing the Audit Trail Records

A definition of each column in the Audit Trail log is listed in Table 15-1.

Table 15-1 Audit Trail Column Definitions

Column

Definition

Date

Date when the action occurred in the format MM/dd/yy HH:mm:ss

Num

Incrementing count of actions

User

User ID that initiated the action

P/F

Pass/Fail (that is, whether or not the action was executed)

Operation

Action that was taken

Step 4 Right-click on the column headings to display the list in ascending-to-descending or descending-to-ascending order.

Step 5 Left-click on the column heading to display the following options:

•Reset Sorting—Resets the column to the default setting.

•Hide Column—Hides the column from view.

•Reset Columns Order/Visibility—Displays all hidden columns.

•Row Count—Provides a numerical count of log entries.

Step 6 Shift-click on the column heading for an incremental sort of the list.

Stop. You have completed this procedure.

NTP-A214 Off-Load the Audit Trail Record

Purpose

This procedure describes how to off-load up to 640 audit trail log entries in a local or network drive file to maintain a record of actions performed for the node. If the audit trail log is not off-loaded, the oldest entries are overwritten after the log reaches capacity.

Step 5 In the Archive Audit Trail dialog box, navigate to the directory (local or network) where you want to save the file.

Step 6 Enter a name in the File Name field.

You do not have to give the archive file a particular extension. It is readable in any application that supports text files, such as WordPad, Microsoft Word (imported), etc.

Step 7 Click Save.

The 640 entries are saved in this file. The next entries continue with the next number in the sequence, rather than starting over.

Note Archiving does not delete entries from the CTC audit trail log. However, entries can be self-deleted by the system after the log maximum is reached. If you archived the entries, you cannot reimport the log file back into CTC and will have to view the log in a different application.

Stop. You have completed this procedure.

NTP-A306 Off-Load the Diagnostics File

Purpose

This task describes how to off-load a diagnostic file. The diagnostic file contains a set of debug commands run on a node and its results. This file is useful to Cisco Technical Support (TAC) when troubleshooting problems with the node.

Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could pose an eye hazard. Statement 1056

Step 1 Using an inspection microscope, inspect each fiber connector for dirt, cracks, or scratches.

Step 2 Replace any damaged fiber connectors.

Note Replace all dust caps whenever the equipment is unused for 30 minutes or more.

The Port and Service State columns identify the port number and current service state (In-Service and Normal [IS-NR], Out-of-Service and Management, Disabled [OOS-MA,DSBLD], or Out-of-Service and Management, Maintenance [OOS-MA,MT]) for each port. The Loopback Type column identifies the type of loopback (None, Terminal [Inward], or Facility [Line]) applied to each port on the card.

Indicates the timing clock. The report section that follows applies to the timing clock indicated.

NE

The node timing clock.

BITS-1 Out

The BITS-1 Out timing clock.

BITS-2 Out

The BITS-2 Out timing clock.

Status

Indicates the status of the timing clock.

INIT_STATE

The timing reference has not been provisioned. For an NE reference, this status appears just before the first provisioning messages when the TCC2/TCC2P is booting. Timing is provisioned to the internal clock of the node.

HOLDOVER_STATE

The clock was locked onto a valid timing reference for more than 140 seconds when a failure occurred. Holdover state timing is a computation based on timing during normal state combined with the node's internal clock. The node holds onto this frequency until the valid reference is restored. This status appears for NE references only.

FREERUN_STATE

The node is running off its internal clock without any modification except the calibrated value to bring timing to 0 PPM. Freerun state can occur when a Force switch to the Internal clock is initiated, all references fail without the 140 seconds of holdover data, or only Internal timing references are defined. This status appears for NE references only.

NO_SYNC_STATE

A synchronization timing reference is not defined. BITS-1 Out or BITS-2 Out default to this status until an OC-N card is defined as its reference on the Provisioning > Timing tab. This status appears for external references only.

NE_SYNCH_STATE

BITS-1 Out and BITS-2 Out use the same timing source as the NE. This is displayed when NE Reference is selected for BITS-1 Out and BITS-2 Out Reference List on the Provisioning > Timing tab.

NORMAL_STATE

The timing reference is locked onto one of its provisioned references. The reference cannot be Internal or no sync state.

FAST_START_STATE

The node has switched references, but the reference is too far away to reach normal state within an acceptable amount of time. Fast Start is a fast acquisition mode to allow the node to quickly acquire the reference. After it achieves this goal, the node progresses to the normal state.

Status (cont.)

FAST_START_FAILED_STATE

A timing reference is too far away to reach in normal state. The fast start state could not acquire sufficient timing information within the allowable amount of time.

Status Changed At

Date and time of the last status change.

—

Reference

Indicates the timing reference.

Three timing references (Ref-1, Ref-2, and Ref-3) are available on the Provisioning > Timing tab.

These options indicate the timing references that the system uses, and the order in which they are called. (For example, if Ref-1 becomes available, Ref-2 is called.)

Selected

Indicates whether the reference is selected.

Selected references are indicated with an X.

—

Facility

Indicates the timing facility provisioned for the reference on the Provisioning > Timing tab.

BITS-1

The timing facility is a building integrated timing supply (BITS) clock attached to the node's BITS-1 pins.

BITS-2

The timing facility is a BITS clock attached to the node's BITS-2 pins.

OC-N card with port #

If the node is set to line timing, this is the OC-N card and port provisioned as the timing reference.

Internal clock

The node is using its internal clock.

State

Indicates the timing reference state.

IS

The timing reference is in service.

OOS

The timing reference is out of service.

Condition

Indicates the timing reference state.

OKAY

The reference is valid to use as a timing reference.

OOB

Out of bounds; the reference is not valid and cannot be used as a timing reference, for example, a BITS clock is disconnected.

Condition Changed

Indicates the date and time of the last status change in MM/DD/YY HH:MM:SS format.

—

—

SSM

Indicates whether SSM is enabled for the timing reference.

Enabled

SSM is enabled.

Disabled

SSM is not enabled.

SSM Quality

Indicates the SSM timing quality.

8 to 10 SSM quality messages might be displayed.

For a list of SSM message sets, see the Cisco ONS 15454 Reference Manual.

SSM Changed

Indicates the date and time of the last SSM status change in MM/DD/YY HH:MM:SS format.

b. Verify that no unexplained alarms appear on the network. If unexplained alarms appear, resolve them before continuing. Refer to the Cisco ONS 15454 Troubleshooting Guide if necessary.

Step 4 Determine the active cross-connect card (XCVT/XC10G/XC-VXC-10G). The ACT/STBY LED of the active card is green. The ACT/STBY LED of the standby card is amber.

Note You can also place the cursor over the card graphic to display a popup identifying the card as active or standby.

Step 5 If you want to replace the active cross-connect card, you must switch it to standby first by completing the following substeps. If you want to replace the standby card, skip this step and continue with Step 6.

a. In the node view, click the Maintenance > Cross-Connecttabs.

b. Under Cross Connect Cards, choose Switch.

c. Click Yes in the Confirm Switch dialog box.

Note After the active XCVT/XC10G/XC-VXC-10G goes into standby, the original standby slot becomes active. This causes the ACT/STBY LED to become green on the former standby card.

The replacement card boots up and becomes ready for service after approximately one minute.

Stop. You have completed this procedure.

Caution The 15454-FTA3 and 15454-FTA3-T fan-tray assemblies can only be installed in ONS 15454 R3.1 and later shelf assemblies (15454-SA-ANSI, P/N: 800-19857-xx; 15454-SA-HD, P/N: 800-24848-xx). The fan-tray assembly includes a pin that prevents it from being installed in ONS 15454 shelf assemblies released before ONS 15454 R3.1 (15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1, P/N: 800-07149). Equipment damage can result from attempting to install the 15454-FTA3-T or 15454-FTA3 in an incompatible shelf assembly.

Caution 15454-CC-FTA is compatible with Software R2.2.2 and greater. It is compatible with shelf assemblies 15454-SA-ANSI and 15454-SA-HD.

Caution As with the FTA3, the 15454-CC-FTA Fan Fail LED on the front of the fan-tray assembly illuminates when one or more fans fail to indicate that a fan-tray assembly or AIP replacement is required. But the Fan Fail LED on the 15454-CC-FTA will also illuminate when only one power source is connected to the chassis, and or any fuse blows. In such conditions, the Fan Alarm is triggered and the fans run at maximum speed.

Caution Do not force a fan-tray assembly into place. Doing so can damage the connectors on the fan tray and/or the connectors on the backplane.

Note The 15454-SA-ANSI or 15454-SA-HD shelf assembly and 15454-FTA3, 15454-FTA3-T, or 15454-CC-FTA fan-tray assembly are required with the ONS 15454 XC-10G, OC-192, and OC-48 any slot (AS) cards.

Note To replace the fan-tray assembly (FTA), it is not necessary to move any of the cable management facilities.

Step 1 Review Table 15-3 to ensure that you have compatible components when replacing the fan-tray assembly and note the alarms that will occur when an incompatibility occurs.

Note If you need to determine the hardware that has been installed on a node, click the Inventory tab in node view.

Step 8 If you are replacing the fan-tray air filter and it is installed beneath the fan-tray assembly, slide the existing air filter out of the shelf assembly and replace it before replacing the fan-tray assembly.

If you are replacing the fan-tray air filter and it is installed in the external bottom bracket, you can slide the existing air filter out of the bracket and replace it at anytime. For more information on the fan-tray air filter, see the "NTP-A107 Inspect and Replace the Air Filter" procedure.

Step 9 Slide the new fan tray into the shelf assembly until the electrical plug at the rear of the tray plugs into the corresponding receptacle on the backplane.

Step 10 To verify that the tray has plugged into the backplane, check that the LCD on the front of the fan tray is activated.

Step 11 If you replace the door, be sure to reattach the ground strap.

Stop. You have completed this procedure. Estimated time of replacement by a skilled technician is two minutes.

NTP-A290 Replace the Alarm Interface Panel

Purpose

This procedure replaces the alarm interface panel (AIP) with a new AIP on an in-service node without affecting traffic; however, shared packet rings might need to be deleted and rebuilt after the repair procedure. Ethernet circuits that traverse nodes with a software release prior to R4.0 will be affected.

Warning The covers are an integral part of the safety design of the product. Do not operate the unit without the covers installed. Statement 1077

Caution Do not use a 2A AIP with a 5A fan-tray assembly; doing so will cause a blown fuse on the AIP.

Caution If any nodes in an Ethernet circuit are not using Software R4.0 or later, there is a risk of Ethernet traffic disruptions. Contact the Cisco Technical Support at 1 800 553-2447 when prompted to do so in the procedure.

Caution Always use the supplied ESD wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.

Note Perform this procedure during a maintenance window. Resetting the active TCC2/TCC2P card can cause a service disruption of less then 50 ms to OC-N or DS-N traffic. Resetting the active TCC2/TCC2P card can cause a service disruption of 3 to 5 minutes on all Ethernet traffic due to spanning tree reconvergence if any nodes in the Ethernet circuit are not using Software R4.0 or later.

Step 1 Review Table 15-3 to ensure that you have compatible components when replacing the fan-tray assembly and note the alarms that will occur when an incompatibility occurs.

Step 2 Ensure that all nodes in the affected network are running the same software version by completing the following substeps before replacing the AIP and repairing circuits:

b. In network view, click the Maintenance > Software tabs. The working software version for each node is listed in the Working Version column.

c. If you need to upgrade the software on a node, refer to the release-specific software upgrade document for software upgrade procedures. No hardware should be changed or circuit repair performed until after the software upgrade is complete. If you do not need to upgrade software or have completed the software upgrade, proceed to Step 3.

Step 3 Record the MAC address of the old AIP:

a. If you are using a single IP address "repeater" configuration, click the Provisioning > Network > General tab.

Step 5 Unscrew the five screws that hold the lower backplane cover in place (Figure 15-7).

Figure 15-7 Lower Backplane Cover

Step 6 Grip the lower backplane cover and gently pull it straight away from the backplane.

Step 7 Unscrew the two screws that hold the AIP cover in place.

Step 8 Grip the cover and gently pull away from the backplane.

Note On the 15454-SA-HD (P/N: 800-24848), 15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1 (P/N: 800-07149) shelves, the AIP cover is clear plastic. On the 15454-SA-ANSI shelf (P/N: 800-19857), the AIP cover is metal.

Step 9 Grip the AIP and gently pull it away from the backplane.

Step 10 Disconnect the fan-tray assembly power cable from the AIP.

Step 11 Set the old AIP aside for return to Cisco.

Caution The type of shelf the AIP resides in determines the version of AIP that should replace the failed AIP. The 15454-SA-ANSI shelf (P/N: 800-19857) and 15454-SA-HD (P/N: 800-24848) currently use the 5A AIP, (P/N: 73-7665-01). The 15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1 (P/N: 800-07149) shelves and earlier use the 2A AIP (P/N: 73-5262-01).

Caution Do not put a 2A AIP (P/N: 73-5262-01) into a 15454-SA-ANSI shelf (P/N: 800-19857) or 15454-SA-HD (P/N: 800-24848); doing so will cause a blown fuse on the AIP.

Step 12 Attach the fan-tray assembly power cable to the new AIP.

Step 13 Place the new AIP on the backplane by plugging the panel into the backplane using the DIN connector.

Step 14 Replace the AIP cover over the AIP and secure the cover with the two screws.

Step 15 Replace the lower backplane cover and secure the cover with the five screws.

Caution Cisco recommends that TCC2/TCC2P card resets be performed in a maintenance window to avoid any potential service disruptions.

Step 16 Reset the standby TCC2/TCC2P card:

a. Right-click the standby TCC2/TCC2P card and choose Reset Card.

b. Click Yes in the Resetting Card dialog box. As the card resets, a loading (Ldg) indication appears on the card in CTC.

Note The reset takes approximately five minutes. Do not perform any other steps until the reset is complete.

Note The CTC session freezes until all circuits are repaired. Circuit repair can take up to five minutes or more depending on the number of circuits provisioned.

When the circuit repair is complete, the Circuits Repaired dialog box appears.

Step 26 Click OK.

Step 27 In the node view of the new node, click the Circuits tab. Check to ensure that all circuits listed have a status of DISCOVERED. If all circuits listed are not DISCOVERED, call the Cisco Technical Support to open a Return Material Authorization (RMA). See the "Obtaining Documentation and Submitting a Service Request" section.

Step 4 Grip two of the jack screws and use them to carefully pull the UBIC-V away from the shelf.

NTP-A336 Edit Network Element Defaults

Purpose

This procedure edits the NE defaults using the NE Defaults editor. The new defaults can either be applied only to the node on which they are edited or exported to a file and imported for use on other nodes.

Step 3 Under Defaults Selector, choose a card type (if editing card-level defaults), CTC (if editing CTC defaults), or NODE (if editing node-level defaults). Clicking on the node name (at the top of the Defaults Selector column) lists all available NE defaults in the Default Name column. To selectively display just the defaults for a given card type, for node-level, or for CTC-level, you can drill down the Defaults Selector menu structure.

Step 4 Locate a default you want to change under Default Name.

Step 5 Click in the Default Value column for the default property you are changing and either choose a value from the drop-down menu (when available), or type in the desired new value.

Note If you click Reset before you click Apply,all values will return to their original settings.

Step 6 Click Apply (click in the Default Name column to activate the Apply button if it is unavailable). You can modify multiple default values before applying the changes.

A pencil icon will appear next to any default value that will be changed as a result of editing the defaults file.

Step 7 If you are modifying node-level defaults, a dialog box appears telling you that applying defaults for node level attributes overrides current provisioning and asks if you want to continue. Click Yes.

If you are modifying the IIOP Listener Port setting, a dialog box appears warning you that the node will reboot and asks if you want to continue. Click Yes.

Note Changes to most node defaults reprovision the node when you click Apply. Changes made to card settings using the Defaults Editor do not change the settings for cards that are already installed or slots that are preprovisioned for cards, but rather, change only cards that are installed or preprovisioned thereafter. To change settings for installed cards or preprovisioned slots, see Chapter 10 "Change Card Settings."

Note Changing some NE defaults can cause CTC disconnection or a reboot of the node in order for the default to take effect. Before you change a default, view the Side Effects column of the Defaults editor (right-click a column header and select Show Column > Side Effects) and be prepared for the occurrence of any side effects listed for that default.

Stop. You have completed this procedure.

NTP-A337 Import Network Element Defaults

Purpose

This procedure imports the NE defaults using the NE Defaults editor. The defaults can either be imported from the CTC software CD (factory defaults) or from a customized file exported and saved from a node.

Note For a list of card and node default settings, refer to the "Network Element Defaults" appendix in the Cisco ONS 15454 Reference Manual.

Step 4 If the correct file name and location of the desired file do not appear in the Import Defaults from File dialog box, click Browse and browse to the file you are importing.

Step 5 When the correct file name and location appear in the dialog box (the correct file name is 15454-defaults.txt if you are importing the factory defaults), click OK.

A pencil icon will appear next to any default value that will be changed as a result of importing the new defaults file.

Step 6 Click Apply.

Step 7 If the imported file fails to pass all edits, the problem field shows the first encountered problem default value that must be fixed. Change the problem default value and click Apply. Repeat until the imported file passes all edits successfully.

Step 8 If you are modifying node-level defaults, a dialog box appears telling you that applying defaults for node level attributes overrides current provisioning and asks if you want to continue. Click Yes.

If you are modifying the IIOP Listener Port setting, a dialog box appears warning you that the node will reboot and asks if you want to continue. Click Yes.

Note The defaults currently displayed are exported whether or not they have been applied to the current node.

Note The NE defaults can also be exported from the File > Export menu. These exported defaults are for reference only and cannot be imported.

Step 4 If the desired file to export to does not appear in the Export Defaults to File dialog box (or does not yet exist) click Browse and browse to the directory where you want to export the data; then either choose or type in (to create) the file to export to [the defaults will be exported as a text file delimited by equals (=) signs].

Step 4 To enable BERT on the DS1/E1-56 cards, choose one of the following options from the TPGM-Selection drop-down list:

•TPGM-L—Enables the test pattern generation and monitoring on the line side.

•TPGM-B—Enables the test pattern generation and monitoring on the backplane side. You can enable TPGM-B on a port only if that port has a bidirectional circuit.

•None—Disables the BERT mode.

Go to Step 7.

Step 5 To change the test pattern from Test Pattern Generator and Monitor-Line (TPGM-L) to Test Pattern Generator and Monitor-Backplane (TPGM-B) or vice versa, choose the following options from the TPGM-Selection drop-down list in a sequence:

•None—Stops the previous test pattern that is executed.

•TPGM-L or TPGM-B—Enables the test pattern generation and monitoring on the line side or the backplane side.

Go to Step 7.

Step 6 To enable BERT on the DS3XM-12 cards, select the DS1 or DS3 tab. From the TPGM-Selection drop-down list, choose the required option:

•(Only DS1) TPGM-B—Enables test pattern generation and monitoring on the backplane side. You can enable TPGM-B on a port only if that port has a bidirectional circuit.

•(Only DS3) TPGM-L—Enables test pattern generation and monitoring on the line side.

•None—Disables the BERT mode.

Go to Step 7.

Note While reverting CTC to a version lower than Release 8.5, disable BERT on the DS3XM-12 cards.

Step 7 Choose a test pattern from the drop-down list. The available test patterns are PRBS15, PRBS20, PRBS23, QRSS, and ALT1s0s (alternating ones and zeroes).

Note When testing with PRBS15 or PRBS23 BERT signals on the DS3XM-12 card, you need to set the PRBS pattern to inverted mode on test equipment that follow the ITU-T standard 0.150.

Step 8 Click Apply.

Step 9 Click the Test Mode subtab. In the test mode you can inject error bits and monitor the error count on the traffic running on a port.

Note You can inject errors only if the Synchronization Status is True.

The Synchronization Status column displays the connection status between the test pattern generator (TPG) and test pattern monitor (TPM). If the status is True, then synchronization between TPG and TPM conforms to the test pattern that is configured.
